Choroidal osteoma is a rare, benign, osseous choristoma presenting as an orange-yellow, well-defined fundus mass. It presents unilaterally in most cases, has a predilection for the female sex, and favor a juxtapapillary location, becoming clinically manifest when it involves the macula. Almost 60% of eyes with osteoma may suffer significant visual loss. Choroidal osteomas can easily be mistaken for other conditions with similar presentations. We herein report two rare cases presentation of choroidal osteoma: a 74-year-old male with 2-year blurred vision in the right eye (RE) initially misdiagnosed with age-related macular degeneration received intravitreal injections and after a multimodal evaluation, following cataract surgery in RE, confirmed to be choroidal osteoma and a 19-year-old female with a history of choroidal hemangioma presented with blurred vision in her left eye (LE), with examination revealed an irregular orange-yellow lesion along the superotemporal arcade with serous macular detachment, later diagnosed as choroidal osteoma.
